10. AUTOMATICS
We can deliver the following items to the units:
- Supply and control box: Surface-mounted in the closed casing (equipped with a main switch,
overcurrent circuit breakers, short-circuit protection devices, signalling lamps), intended to
cooperate and control the elements of automatics.
One control box allows controlling a group of the units by means of single thermostat in the
AUTOMAT|MANUAL operation mode.
The supply and control box (1~230V/50Hz) should be from the main switchboard equipped with a
main switch and differential protection device.
When the automatics are ordered with the unit the electric diagrams of the unit and automatics are
delivered by the company as well.
The exemplary connection diagrams of the units with single-phase motors are presented in the
pictures 2, 3, 4 and 5.
- Rotational speed controllers of the fan: The transformer 5-step rotational speed controllers ARW
(1~230V/50Hz) allow controlling the air delivery and thermal power. The individual rotational speed
steps are selected manually.
